AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/CESSNA 170/24 Amdt 2.

Cessna 170, 172, F172, FR172 and 175 Series Aeroplanes

AD/CESSNA 170/24 Amdt 2 Aileron Mass Balance Weight
Attachment Rivets 8/2008

Requirement:	CANCELLED.
This AD is cancelled on 31 July 2008.
Background:	This unique Australian AD, issued in 1985, required, at each issue of a new maintenance release, inspection of the aileron mass balance weight attachment rivets for corrosion.  The Significant Defect Reporting data base revealed no defects have been reported on this aircraft model since 1980.  As this type of inspection would be carried out during normal maintenance, this AD is no longer required.

Delegate of the Civil Aviation Safety Authority
